. v 'l Chil. ((5189-4-72) Thisinvention relates to improvements in window construction especially adapted for use with cars fand buses, and has for its lprincipal object improved means for mounting the slidable portion ofthe window. v s

The'new improved features will be pointed out in the detailed description which follows. accompanied'by the annexed drawings wherein: v Figure l is a cross-section through a part of the l0 vwindow at the point where the slldble Window sash lmeets a fixed or transome portion of the window.

Figure2 is afront elevation showing the righthand portion of the window and frame. l5 Figure 3 is a perspective view of my improved form of `spring and its cooperating channel memberasshowninFigurel.

Figure 4 is a. fragmentaryview, part inelevation and part in section, through the channel member, showing one ofthe rack devices used in connection with the lock bolt shown in ure 2.

lFigure 5 is a view of Figure 4 looking from right to left. s Figure 6 is a view similarV to Figure 4 but showing a slightly modified form of rack member.

Figure 'I is a perspective view of the rack mem-,f

ber shown in Figure 4.

Figure 8 is a view showing a slight modication of the construction of the channel member and the weather strip.

Referring now to the details, wherein like numbers refer to corresponding parts in the various views, i is a vertical post of a window, ,to which is s fastened a guide member 2, this fastening being made by a plurality of screws, one of which: 2, is shown, the same passing through a seat portion 4 preferably forming an integral part of the guide member 2. The guide member {carries a U-f shaped sash member 5 which is adapted to receive a glass pane l, the same being held in the sash member 5 by a suitable sizing strip 1. Fastened to the stile or sash member 5, in any satisfactory manner as by suitabley cement, is

a weather strip (made of felt or other suitable material which will slide in the guide member 2.

Mounted between the weather strip I and the seat 4, is a channel-shaped member having its sides l and l0 extending toward the seat l. As

u shown in Figures l and 3, the channel has part of `its base Il depressed away from the weather f strip l whereby the weather strip I only contacts with the oppositely disposed portions I2 and I2 on the channel member. The purpose of this will be later pointed out.

The sides l and ll of the channelmember have their free edges turned toward each other and bent inwardly as indicated at I4 and Il. Positioned between the channel member and the seat 4 is a Z-shaped strip spring Il having one side l1 5 engaging the seat I and one bent portion il en gaging the end of the side member l when the parts are assembled as shown in Figure l. The ,l side I9 of the spring member Ii, which is more remote from the seat 4, has its free edge 2l ex- LQ tending within the channel and formed to snugly nt the formation of the side I2 of the channel,

' as is clearly shown in Figures l and 3. This im proved construction of the Z spring allows the same to be easily assembled'or replaced. While- .l some forms of the Z spring have been .used in l the past in somewhat similar relation, the free edge thereof, corresponding to the part 2l, has been positioned outside of the channel and rigidly fastened thereto as by'spot-welding, such a con- 80 struction beingv illustrated in Conway Patent 2,012,156, issued August 20, 1935. My improved construction provides a much easier and cheaper method of assembly if, forany reason, the pressure spring Il should become broken or lose its'v 2l tension.

The depressed surface Il of the channel member has one or more openings 2l therein disposed longitudinally of its length to accommodate a rack member 22 which may be a single member. 30 as shown in Figure 7, or a plurality of individual rack members may be used. or the rack may be composed of a continuous strip formed to the right contour adiacent the openings 2i. In any case.the rack member 22 is preferably formed as 3.3

`shown in Figures 4 and 7, the ends 22 and 2l being fastened to the inner surface of the portion Il in any satisfactory manner as by spot-welding at the points 25 and 2l. The rack member 22 has rounded or curved surfaces 2l and 22, the latter of 4,0 which, at least, is positioned so as to come substantially flush with the outer face 2l of the depressed portion il, so that the lookbolt Il, controlled by the lever 2i, will pass smoothly along the runway formed by the depressed portion Il 45 and without sharply encountering the edges 32 of the openings 2|, thereby providing a smoother action of the window when it is raised and lowered.

As shown in Figure 6, the rack member 22 has 50 formations somewhat differingfrom 21 and 2l, but nevertheless the rounded, portions, corresponding to 21 and 2l, may come substantially hush with the lock bolt track line or surface 22. By mounting the channel member in reverse l! position from .that shown in the Conway patent, to which reference has been made, the opening between the sides of the channel will face the bottom of the runway in the guide member 2 into which the assembly is placed and operates. This construction of the assembly overcomes the objection of appearance of the opening between the sides of the channel over the top of the sash, and thereby eliminates accumulation of dust and dirt in the channel member. Furthermore, by havingthe depressed portion l I in the channel member, the weather strip 8 does not come in contact with this surface which always has a tendency to be more or less roughened by the end 380i the sash lock bolt as the window is raised and lowered. Thus the continuously smooth surfaces I2 and I3 are always in contact with-the weather strip 8.

No description is made of the transome member 33 as this fixed portion of the window forms no part of my present invention. Neither is `the sash lock bolt described in detail as this form no part of my present invention.

It may be said, in passing, that the side member 34, forming a part of the guide member 2, may be fastened in position after the Window sash is located, in any satisfactory manner somewhat as shown in the Conway patent heretofore referred to. Also, a packing or weather strip 35 is preferably used at the point indicated in Fig-- ure 1.

As will be seen by reference to Figure 8, my invention is susceptible of certain modifications; for example, the base 36 of the channel member may be perfectly flat and a recess 31 formed in the weather strip 8, so that, as heretofore described, the weather strip will not contact with the sash bolt runway surface on the base 36. However, such modifications of the details to which my invention is directed are believed to come within the scope of the appended claims. .What I claim is: t

l. In a window construction having a guide member with a seat portion and being fastened to a window frame, a sash member for receiving a glassv pane' and carrying aweather strip to move with it in the guide member, a channelshaped member located within the guide member with at least a part of the base ofthe channel member in contact with said weather strip, and the sides of the channel member extending toward the seat of the guide member, a Z-shaped strip spring positioned between said seat and the channel member, and a rack member fastened to the interior surface of the base of the channel member and having a portion extending into an opening in said base as and for the purpose described. 4
